Continental Patterns of Phenotypic Variation Along Replicated Urban Gradients: A Mega‐AnalysisNARA Subscribed
Individual variation among and within natural populations can have eco‐evolutionary implications by, for example, affecting species interactions or evolutionary potential. Urban systems present a unique opportunity to evaluate how environmental change shapes variation since urban phenotypic differentiation is widely documented on contemporary timescales. We introduce and test three hypotheses to determine how urbanisation affe...
Reducing Fire Severity and Extent Bolsters Subalpine Forest Resilience to Global Change Through Key Demographic PathwaysNARA Subscribed
High‐elevation subalpine forests are experiencing rapid changes in climatic conditions, biological disturbances, and wildfire regimes. Despite this, evidence is mixed as to whether they will undergo major ecological transformation or be resilient to a confluence of global change drivers. Here we use subalpine fir ( Abies lasiocarpa ) and Englemann spruce ( Picea engelmannii ), which form co‐dominant forests through much of the...
Spatial distribution of selenium-mercury in Arctic seabirdsNARA Subscribed
Climate change is transforming bioenergetic landscapes, challenging behavioral and physiological coping mechanisms. A critical question involves whether animals can adjust behavioral patterns and energy expenditure to stabilize fitness given reconfiguration of resource bases, or whether limits to plasticity ultimately compromise energy balance. In the Arctic, rapidly warming temperatures are transforming food webs, making Arct...
Purpose There is an increasing interest in the use of non-nutritive sweeteners to replace added sugar in food and beverage products for reasons of improving consumer health. Much work has been done to understand safety of sweeteners, but very little on sustainability. To address that gap, this study presents the results of a life cycle assessment (LCA) of production of rebaudioside A 60%, 95% pure (RA60) steviol glycoside mix...
The application of irrigation water and nitrogen (N) fertilizer in excess of crop demand reduces profitability and has multiple detrimental impacts on the environment. N dynamics in agro‐ecosystems are extremely complex, and mechanistic crop models are most often required to quantify the impact of improved management practices on reducing fertilizer N losses. In this study, life cycle assessment (LCA) methodology and mechanist...
Discharge‐based economic valuation of irrigation water: Evidence from the Teesta River, BangladeshNARA Subscribed
Studies estimating the value of irrigation water as a function of river discharge are rarely found in the literature; however, discharge‐based valuation carries significance when the in‐ and off‐stream uses are evaluated for optimal water allocation. This paper develops the total and marginal benefit functions of the key off‐stream water use, irrigation, as a function of flow in the Teesta River of Bangladesh. The field water...
Irrigation Sustainability Assessment of Selected Projects in Tha Chin Basin, ThailandNARA Subscribed
This study assesses the sustainability of the Kamphaengsaen (KPP) and Phophraya (PPP) projects located in the Tha Chin Basin, Thailand. The assessment is based on the investigation of sustainability indicators using principal component analysis. The dominant indicators affecting sustainability are identified. The key indicators are weighted and computed to obtain the irrigation sustainability index (ISI) used to classify the s...
Variability in smallholders' irrigation water values: Study in North‐West Province, South AfricaNARA Subscribed
Capturing the economic value of water use is an integral part in the design of economic incentives and institutional arrangements that can ensure sustainable, efficient and equitable allocation of water. Irrigation water values of small‐scale irrigators are, however, seldom studied and too little attention is paid to the determinants of the variability of water values. In South Africa issues like the call for more efficient wa...
